Astronomers have long struggled to explain the unusual chemical composition of an ancient star, with no theory matching observations. A new laboratory experiment reproducing extreme stellar conditions has now provided an explanation for the star's chemistry, resolving a long-standing astrophysics puzzle. The findings connect lab physics directly to stellar observation and are drawing attention in the astronomy community.

Chemists report detecting a crown-shaped ring made of sulfur atoms inside mammalian cells, a structure long theorised but rarely observed in living systems. The finding, covered by Chemical & Engineering News, could reshape understanding of sulfur chemistry in biology, since reactive sulfur species are involved in cell signalling and metabolism. Researchers say confirming such unusual sulfur rings in cells opens new questions about how they form and what roles they play in health and disease.

Researchers have developed a catalyst stable in water that can form carbon-carbon bonds, a key reaction in organic chemistry, under conditions compatible with living cells. The advance could open the door to using powerful catalytic chemistry inside biological systems. Interest centers on what this means for drug development and chemical biology.

Researchers report a new catalyst that makes olefin metathesis, a powerful carbon-carbon bond-forming reaction, work under biological conditions for the first time. Announced via Newswise, the advance could let chemists perform this Nobel-recognized transformation inside living systems or aqueous environments, opening doors to bio-compatible synthesis, drug development and chemical biology applications previously out of reach.

NOAA Fisheries is highlighting a collection of 2.5 million tiny specimens described as perfect little time capsules of ocean chemistry. The samples preserve records of past ocean conditions, helping scientists track changes in temperature, salinity and marine ecosystems over time. The agency frames the collection as a valuable resource for understanding long-term ocean change.

Coatings company Nanize has developed a PFAS-free coating technology aimed at meeting tightening global regulations on so-called forever chemicals. Regulators in Europe and the United States are increasingly restricting per- and polyfluoroalkyl substances, pushing manufacturers to find alternatives. The announcement highlights growing industry demand for high-performance coatings that do not rely on PFAS chemistry.

New analysis of Cassini spacecraft data shows a surprising diversity of salt grains in the plumes erupting from Enceladus, Saturn's icy moon. The findings suggest the ocean beneath its surface varies in composition and chemistry, strengthening the case that Enceladus is one of the most promising places to look for conditions suitable for life beyond Earth.

Patrick Mahomes and Travis Kelce connected on a 48-yard pass on the opening play of the game against the Miami Dolphins, per NFL.com. The strike immediately put the Dolphins' defense under pressure and highlighted the enduring chemistry between the Kansas City quarterback and his star tight end, drawing attention as an early highlight of the matchup.

Dutch renewable chemistry company Avantium has announced the startup of its Flagship Plant in Delfzijl, producing its first batch of FDCA (furandicarboxylic acid), a key building block for plant-based plastics such as PEF. The milestone moves the company from pilot scale toward commercial supply of sustainable alternatives to fossil-based packaging materials.

The president of the UUDPC, the French union of physics and chemistry teachers, has given an interview on the Café pédagogique, a platform for education discussions. He offers a diagnosis of the state of science teaching considered fair by readers, along with simple proposals to improve it. Educators are sharing and endorsing the interview, particularly teachers in secondary schools discussing working conditions and classroom practice.

San Antonio Spurs rookie Dylan Harper is drawing laughs across the NBA community after dropping the usual diplomatic line about coming off the bench and admitting his real feelings instead. Fans joked that he managed the standard PR answer for only seconds before getting candid, with quips about team chemistry taking a hit. The moment has become a lighthearted talking point around the rookie's adjustment to his role in San Antonio.

The Dallas Stars traveled to Traverse City, Michigan, for a team trip that the club describes as a "perfect environment" for bonding. Players and staff spent time together away from the rink as part of the team's efforts to strengthen chemistry and cohesion within the group.

Alan Ritchson and Maria Sten's on-screen dynamic from Reacher carries over unchanged into the upcoming spin-off Neagley, with Sten reprising her role as Frances Neagley. Early coverage suggests fans of the Prime Video series can expect the same chemistry between Reacher and Neagley that made the original show popular, fueling anticipation for the spin-off's release.

Aaron Rodgers hit Garrett Wilson in stride for a big gain in the Steelers' NFL matchup, a connection that quickly drew attention from football fans. The play is being shared as a highlight of the game, with Steelers supporters discussing the Rodgers-to-Wilson chemistry.

Atlanta Dream guard Allisha Gray and star teammate Rhyne Howard have drawn attention for their close on-court partnership, which is credited as a driving force behind the team's strong season. Coverage highlights how their mutual trust and chemistry have elevated both players' performances and anchored Atlanta's rise in the WNBA standings this year.

Geo TV's new drama serial 'Mohabbat' has premiered with its first episode, starring Feroze Khan and Nawal Saeed, with English-subtitled versions released for international viewers. The launch is drawing strong attention from Pakistani drama fans, with the opening episode generating significant engagement online as audiences react to the lead pair's on-screen chemistry.

Researchers have proposed a chemistry-based early warning system to detect harmful algal blooms before they become dangerous. The approach relies on chemical cues released by the bloom-forming organisms, potentially giving coastal communities and aquaculture operators advance notice of toxic events. A Phys.org article covers the work and links to the underlying open-access paper, which has drawn interest among ocean and pollution researchers.

The Dallas Stars travelled to Traverse City, Michigan, for a trip the team describes as a "perfect environment" for bonding ahead of the season. Players and staff spent time together away from the rink, with the club framing the visit as a way to strengthen relationships and build chemistry within the roster.

One hundred years after Erwin Schrödinger formulated his famous equation, the centenary is drawing attention to how foundational the equation remains. Scientists now use it routinely to model atoms and molecules, helping them predict and fine-tune chemical reactions. Commentators note it transformed physics in the 1920s and continues to underpin modern quantum chemistry and materials research.

General Motors is revisiting its electric vehicle strategy with lithium-manganese-rich (LMR) batteries, a chemistry being promoted as a way to extend driving range and cut costs compared with current cells.
